Can nitrifying bacteria be doing so well that PH is low

[Jdgreef24]

One of the things I’ve thought about recently is how hard it is to get nitrates and phosphates up in my tank. Although I do see coral growth, my Ph is never above 8.0 (via apex and ph meter off amazon) with a skimmer line outside, tons of turnover and not much of a leap when the window is open. I know when processing ammonia, an acid of some sort is produced. How likely is it that my nitrogen cycle is keeping me at 8 because how hard these guys are working?

I would say that’s highly unlikely. As PH is affected by C02 and 02 and not nitrogen. But let’s see what’s others have to say as well. Also I have a hard time getting both of my tanks above 8.0 as well. Same tons of turn over and simmer lines ran outside. At this point I gave up and kept everything else in check.

has no eefect on ph at all.
What test kit(s) are you using to test water ?
